Density of aluminum alloy is low, but the strength is relatively high or more than high quality steel, also good plasticity make it can be processed into a variety of profiles, with excellent electrical conductivity, thermal conductivity and corrosion resistance, widely used in industry, the use of only steel. Aluminum is one of the abundant metal element in the earth's crust, ranking third only after oxygen and silicon. In the metal species, after steel, for the second category of metals.
CNC machining is to make the process more reasonable, is also a common process of aluminum alloy precision machining, the use of multi-direction cutting function of the endmill, spiral cutting interpolation and high cut interpolation, etc., it uses as few tools as possible to process a small number of holes.
In addition to the CNC machining for the hole of aluminum alloy precision parts processing, but also by boring and reaming and other methods for high-precision machining holes. In order to realize the high speed and high precision of boring machining, it is necessary to pay attention to the influence of cutter tooth vibration on the roughness of machining surface and tool life.In order to prevent machining precision and tool life decline, the selected machining center must be equipped with excellent dynamic balance performance of the spindle, and the selected boring tool must also have a high dynamic balance characteristics.
